You might want to read the good tips at the front of the Vintage Air catalog...... vintageair.com

They tell you about sizing a condenser and compressors. Using this, you can source your condenser and compressor from local suppliers (junque resellers, auto stores, etc) and then purchase the evaporator unit from someone. The under dash Vintage Air evap lists for under $300. I realize that there is an argument made about a complete kit being matched....but you can do it.

I built one for a 350 Chevy using a late model truck compressor (96-99 since I had a serpentine belt) and a condenser that was the biggest one that I could get in front of the radiator. I bought a evap and dryer from Vintage Air. Thing works great. Here in Tucson, we need a one speed blower since HIGH is the only setting.
